Windows 8, Lenvo USB 3.0 dock = lag + fuzzy image

[lasse]

Hi,
I have a setup consisting of a Lenovo X1 Carbon, Lenovo USB 3.0 dock (0A33970/1) and two external monitors connected by DVI running at 1920x1200.

I installed the 7.0 M2 driver before connecting the dock to ensure proper installation. So far so god...

However I am having performance issues on the external monitors. scrolling, moving windows around and even moving the mouse pointer causes lag and poor image quality (best described as a fuzzy blink).

I have attached support files for further investigation.
Please help me solve this issue!

[Wim]

Yep - this has come up in similar threads. I think we have managed to reproduce something similar and investigating this at the moment. Hopefully we will have a fix for this in the next release that hopefully will fix these issues on the forum.

Thanks

Wim

[lasse]

Just to let you know. Updated BIOS for my X1C improved the situation. Not nearly fixed, but improved.

[Wim]

Interesting... That might have fixed some USB issues, which would increase the USB throughput and therefore increase the interactivity of DisplayLink. This could help some other users who have been seeing this issue.

My mouse doesn't move very smooth on external monitor connected to DVI on Lenovo USB 3.0 Dock station

I am not playing any video, just working in office tools, notepad, using Chrome and the mouse doesn't move smooth, staggers just a little, but the movement is not as precise as on the notebook screen - which makes the external screen pretty much unusable

:confused: Can you please assist?

I have the exact same problem.
Laggy mouse movement and blurry image when moving stuff around.
Also just using standard office apps.

what is your HW configuration and DisplayLink device?

Everything explained here:

Now running the latest M3 drivers.

[mirezko]

it seems I created a duplicate thread http://www.displaylink.org/forum/showthread.php?t=2145

however, I am using the newest drivers DisplayLink 7.0M3

I will try to get other USB 3 drivers and see if that helps

[mirezko]

bumping post

I couldn't find newer USB drivers that I actually have.
I am waiting for the DisplayLink drivers update.

Is there any tool that can monitor USB 3.0 throughput so I could see if it is being used to 100%?

So far I could find only information in Device Manager and it says 3% (connected external USB driver and DVI 1900x1200 monitor)

[rsenio]

I can verify the same, very annoying, functionality. New Dell XPS 14 Ultrabook, core i7, ssd, Windows 8, latest DisplayLink software etc. Targus USB 3.0 dual video docking station. Nothing but lag, mouse and video, and the occasional garbled video along the task bar, icons. Terrible.

[macros14]

I recently got a new Dell XPS15 running windows 8. I have two large dell monitors running at 1920X1200. When I had both monitors running through displaylink, my logitech mouse was so laggy, it was unusable.

I have since changed my setup a bit so that I only have one monitor running through displaylink and the other connected directly to my laptop. This has helped quite a bit, though now, when my computer is under a little bit of load, my keyboard stops responding. My mouse still works fine. But I have to wait for my keyboard actions to be recognized, which is in the 10/20 second range.

Overall, I am pretty dissatisfied with displaylink and Windows 8, and most of the time find the solution unusable. Hopefully in the near future, some updates will alleviate the issues, but for now having issues with keyboard and/or mouse is a pretty big deal and frustrating.

[rsenio]

http://www.displaylink.org/forum/showthread.php?t=2070

Didn't see this thread? lol

So far I am nothing less than disappointed with "DisplayLink" Using the dual monitors, mouse, keyboard etc through the Displaylink dock station is one awful experience. Close to completely unusable.

[Joe Michaud]

I am having similar issues with my Toshiba Portege Z935-P300 after upgrading to Window 8. (Windows 7 worked great)

Setting the "Optimize for Video" option seems to have helped and has made my docking station much more usable while I wait for the next driver update.

[Sabbasolo]

My Samsung S9 with a Targus docking station exhibits the mouse (Elan trackpad actually) problem quite seriously. I have the M3 drivers and if I turn off displaylink the problem disappears.

It is worse if video is showing on one of the display screens.

I am hopeful it will be fixed soon.

[lasse]

Update to latest drivers 7.1 did not help regarding lag and fuzzy image.
Did a complete uninstall of 7.0 M3 driver - reboot, installation of 7.1 driver - reboot and then connect the docking.

Issues still present. Just to let you know :(

[mirezko]

Update to latest drivers 7.1 did not help regarding lag

I confirm that. The issue with laggy mouse is still present. However it's much better than with 7.0 M3 drivers (Win 8, single 1920x1200, USB 3.0)

[mirezko]

I was forced to downgrade to Windows 7 (due to a bug in SocketAsyncEventArgs)

and I have to say I am really disappointed with this docking station (Lenovo USB 3.0 Dock), it should support 2x DVI monitors, but if this single 1920x1200 is too much for it I can't imagine how it would work with two of these...

Why it can't be as smooth as simple DVI cable? Why would Lenovo even sell this if it doesn't work smooth?

[chrisedwards]

Any update from DisplayLink on this issue? I just bought a USB 3 dock and am experiencing mouse lag on the dock-connected monitor.

Specs:

X1 Carbon (Intel HD 4000 graphics)
Updated to latest BIOS from Lenovo (2.5)
Updated to latest dock firmware from Lenovo
Installed DisplayLink 7.1 M1

Cheers.

[zharry89]

I'm having similar issues:

- laggy mouse
- intermettiet keyboard issues (sometimes it works/sometimes it doesn't)
- fuzzy screen at times

With the same setup

2x DVI 1600-900 monitors
1x USB mouse/keyboard
ASUS Zenbook Prime Touch

I have updated to all the latest USB3 drivers, most current BIOs version available, and latest Displaylink drivers (Feb update). Running latest version of Windows 8 Pro. Still having issues.

Is there a fix coming? What is the timeline? This is frustrating

[fmarines]

Just got a brand new Lenovo X1 Carbon touch and any external monitor, whether connected directly via mini-display port to DVI or DVI to through the USB 3 dock exhibits ongoing grainyness and flickering, as if watching a badly compressed JPEG video...

This is extremely dissapointing as I always work docked!! Help!

[rcreps]

I'll echo this same situation. Been working for a month with X1 Carbon Touch and the Dock issues are extremely frustrating.

[swenkach]

Bumping the same. I'm really not doing anything special. Unboxed laptop, connected displaylink to basic 20" lcd via dvi, and if there is even the slightest activity, i get a bit of a blur. If the monitor is connected directly to the laptop, i don't have any problems.

[Simon]

Hi
I am also using a Lenovo USB 3.0 dock and a X1 Carbon, and I am experiencing the exact same problems; mouse and image lag.
I would like to know if you expect to fix the problems, or if I should be looking for an other dock solution, because this dock do not work sufficiently at the moment!
Regards
Simon

[papaphilya]

I am having the same issue for one of our executive staff and the mouse lag and screen blurryness is unacceptable. any ETA on the solution? Thanks

[carminus]

Yeah same problem. XPS 13 Ultrabook using kensington (3500). Also, the screen blacks out. It's as if the docking station reboots or losses connection with laptop.

Sadly, I can't find a decent competitor for a new docking station or I would jump ship. They are all just rebranded displaylinks.

[djxcee]

I am getting very bad lag with my Sony VAIO VPCZ1. The lag is so unbearable that I must disable video from displaylink to get it to work fine. It is running a 330M Nvidia GFX

I hope you guys can come out with an issue soon.

[stylefish]

hey guys,
i had the exact same problem, but i found a post which resolved my issues (almost) completly.
i'm running a HP dock with DL-3000 series on a samsung notebook.
The Notebook uses the Intel eXtensibile USB host controller.
i found more guys having performance issues using this controller under win8 with usb 3 external drives etc.
so i finally found this tutorial on how to install the original driver from intel (for win7) in windows 8. for me it solves the performance issues!
this is the link, hope it helps :)

This is a major problem. I am so fed up with the jumpy mouse and the fuzzy images.

Can we get SOME word on when this will be fixed? I can barely get any work done.

Ugh.

Buellllllller?

[xijio]

I followed these instructions, now my USB doesn't doesn't work at all. I don't recommend doing this if you've got a Carbon X1 and a Lenovo USB 3.0 dock.

So much for that shimmer of hope :(

Did you uninstall your old DisplayLink drivers and your video drivers first? If so, try Driver Fusion to make sure you got rid of all the NVidia remnants. They like to hang around even after an uninstall.

[stylefish]

the performance gets significantly worse when i disconnect my charger, even with the "new old" drivers from intel.
sorry, xijio for the inconvenience. for me it got better with the drivers but only with the charger connected. a fix / performance improvement for the DL drivers would be really nice...

[Wim]

I've just published the new v7.2 release on our website that should improve this.

It is slightly better than it was before, but I still feel like I'm using a remote desktop on my two attached monitors. There is noticable input lag and screen update lag. The color shifting and blurriness seems to be gone though. Any pointers?

oh and the most anything thing to an end user from an HCI perspective is doing some input and seeing no result. I move my mouse and it doesn't move, 1 second later, it finally moves. Very frustrating!

[jonlove]

Just wanted to echo that I also have the same problem... Windows 7 (64 bit) with the latest Displaylink drivers for the Lenovo USB 3.0 dock.

Very frustrating - it does feel a lot like operating through a remote connection. I have one VGA monitor and one DVI, and it is noticeably worse on the DVI connection (which is higher resolution).

Happy to help debug at all but would be great to find a solution, otherwise having 2 external monitors is not going to last long.

[stylefish]

thanks for the update!
i've tested a bit with the new driver but i think the performance is nearly as slow as before.
if you need some information or can build a beta/debug driver i'm happy to help!

[lasse]

My impressions for 7.2 driver update.

Still running Lenovo X1 carbon and Lenovo USB 3.0 dock with 2 x external monitors and nothing else. Both running DVI @ 1920x1200.

- Blurry image seems to have gone. Moving my mouse pointer over the task bar now does not produce blurry icons.
- Mouse lag still present and even worse than before. Mouse pointer freeze for about one second every few minutes.
- CPU usage still high from the DisplayLinkManager Application 5-30% constant.

So one step forward - one and half back.

[jonlove]

Ignore me - it's still the DVI monitor/highesr res that seems to be worse for me

I am running a 2560x1440 monitor through the HP3005pr USB3.0 dock. I have also had pixelation issues, but after 7.2M0 this is completely gone! :)

I still have minor lag on the mouse from time to time.

cool, thats exactly my setup! but mine is laggy... which chipset and driver / notebook, and which OS do you use?

[jonlove]

So - I swapped out my VGA cable for a DVI. Even though previously the higher res monitor on the DVI cable was slower (and I swapped the other cable), that seems to have helped fix it.

e.g., before I had:
- Monitor 1: DVI -> VGA adapter, VGA cable - running fine
- Monitor 2: DVI cable - running slow

Replaced monitor 1's cable for a straight DVI, and monitor 2 seems to be running normally now.

Not sure if that's helpful or not.

[twisterx]

It is a Samsung series 9 laptop.

PS: In the "Samsung Settings" application, there is a tab called "General - Silent Mode". If I select anything else than "off", the display becomes terribly choppy! This might be a tips for anyone with choppy displays. Check your power saving options!

[chung373]

have there been any updates on this? i got my lenovo carbon x1 with targus dual vido usb 3.0 dock last week and have had nothing but a headache since.

updated both lenovo bios and displaylink drivers to 7.2 and i'm getting the same issues as previous posters where it feels like i'm working on my 2 external monitors through a remote desktop. if i don't do anything besides move the cursor about the screen it's nice and smooth but as soon as hover over buttons/icons, move windows, do any kind of computing it lags up a lot.

for now i've just got one of the externals hooked up via minidp port and it works as it should, but the single monitor still attached to the dock is still laggy.

[Simon]

Hi

The lagging also seems to be gone for me with the new driver..
I have a Lenovo X1 carbon and Lenovo dock..

A thing I have noticed that may be a help to others, is that the minimum processor speed in advanced Power options need to be at least 30% when the computer is plugged in, for the dock to work properly.

You fin the option by going to:
Control Panel->Power options->Choose when to turn off the display->Change advanced power settings->Processor power management->Minimum processor state->Plugget in

My theory is that the minimum speed must be set because the most low power processors have a variable processor speed, to ensure that there is always enough processor time for the Displaylink to be serviced the minimum speed must be set.

Regards.

Hi
My theory is that the minimum speed must be set because the most low power processors have a variable processor speed, to ensure that there is always enough processor time for the Displaylink to be serviced the minimum speed must be set.

This is the same kind of solution that I found using my Samsung Series 9 notebook. Everybody with this kind of problem should investigate the Power Options!

[chrisedwards]

The new drivers + increasing the minimum processor speed in power options have seemed to have mostly solved my issues. I still see occasional mouse lag. Perhaps the displaylink driver should set these power options by default? Or prevent the processor from going into that deep of sleep to begin with?

I have, however, noticed an issue with Windows 8, when a metro app is mounted to the side of the screen, I see the monitors flashing black occasionally. Seems to be a driver issue as this doesn't occur when using built in monitor, and haven't noticed it when plugged into the monitors through displayport.

Scratch that. Lag is still prominent, especially when switching between windows ie (alt-tab). Additionally when copying larger files over ethernet the device will appear to reset (screens go black for a second, ethernet connection is lost).

I'm using 7.2 with two external monitors over DVI on a surface pro with USB3.0 Lenovo dock. I tried hacking up the USB drivers I found in the previously mentioned tutorial thinking it would fix performance, but it hasn't helped.

I can pretty consistently repro the issue by opening Excel, highlighting a cell, hitting ctrl+c (copy) and then when the little animating rectangle around the copied cell starts moving, the screen goes fuzzy/pixelated.

I wish I could say I don't need to use Excel enough for it to matter, but such is the story of my life!

If you make the Excel window not quite maximised on the screen, do you get the same problem?

[mike]

Been following this post for sometime and I'm in the same camp as most.

Win8 Pro on a Lenovo X1 Carbon using the USB3 dock.

The drivers from April 3 made the lag & display situation better than before but not 100% resolved.

The display issue did go away completely as best as I can tell. That was the bit where pictures would be "fuzzy" for a bit especially during transitions. I could always see that during logons but not anymore. So that's good.

However, the mouse lag is still there. It has been improved but you still feel like you're using a remote desktop for sure. I'm using a wired mouse/keyboard to eliminate any wireless issues.

If I can contribute any meaningful info please let me know. Thanks!

[tfennel]

Wim

Yes, the size of the excel window seems to have no effect - same behavior.

Also happens when an IM comes in and the Lync app in the taskbar gets "needy" (blinks/animates) the entire screen goes fuzzy until I activate the needy app.

I have the same problems with a HP Envy x2 notebook: slow performance and disappearing mouse-cursor. I've installed the latest version of the DisplayLink software.

The notebook is running on Windows 8. I'm using a 19" HP LCD monitor with a resolution of 1280x1024. Not very high...

[johnb]

Same issue here with a Thinkpad Helix and USB 3.0 docking running with 2x 24" monitors at 1920x1200 via DVI. OS is Win8 64-bit.

The lag occurs especially when switching from an application displayed on one monitor to another application displayed on the other monitor.

There's also a bit of lag when switching between cells in Excel or switching between applications. For instance: if alt-tabbing from Excel to Outlook, the mouse will "hang" for a sec after alt-tabbing. This is very consistent.

[johnb]

Okay - I managed to fix it.

I updated everything that was available for update in Lenovo System Update.
Including the optional stuff.

My best guess is that it was the BIOS update that fixed it...

Having same issue with my Helix and Targus Universal USB 3.0 DV Docking Station. I can see the mouse skip around. BIOS update didn't solve mine.

[Wim]

Just to try and expand on Dan's post, is it just the mouse that is lagging or is the whole screen freezing for a second? You can check this by just playing a video on the screen at the same time. If the video pauses at the same time the mouse pauses then the screen is freezing for a second or so.

If this is the case then I think we understand what the issue is and working on a fix. We have found a problem and the problem is usually rare, but we suspect it could be timing related so some systems show it a lot more than others. If it was happening often then it would be annoying and would explain the number of users in this thread experiencing it.

If you could confirm if it is just the mouse that lags or if it is the whole screen it would help confirm.

[ThePhantom]

Hi Wim,

I wanted to reply in this thread, as I'm experiencing the periodic momentary freeze, and wanted to give whatever configuration info would be helpful...

First off, I upgraded to 7.2 M1 yesterday (5/11), and it's been light years better than the prior version in nearly every way. The prior 7.2 was maddening under Windows 8 (slow ethernet, incessant unplugging/replugging to get things working after sleep, etc.)

My configuration is:

Plugable UD-3000
Lenovo Twist with Windows 8
DisplayLink monitor set as my main monitor

I get the momentary freeze (1/2 second in length) every few minutes. Both the mouse, as well as any streaming video (SlingPlayer in my case) freeze on the DL display.

I managed to fling the mouse pointer over to the built in notebook's display during the freeze, and it was responsive there -- there were two mouse pointers displayed for that time -- one "frozen" on the DL display, and the responsive one on the notebook's display. The frozen one disappeared once the display "thawed" :)

Once the freeze is fixed, my Windows 8 setup will be nearly perfect. It'll be time to critique my Macbook Air's drivers at that point...

[Galactican]

+1 for this issue with a Lenovo X1 Carbon. I've verified via video that it is the whole screen that is freezing.

[rmvm]

Yep - this has come up in similar threads. I think we have managed to reproduce something similar and investigating this at the moment. Hopefully we will have a fix for this in the next release that hopefully will fix these issues on the forum.

Thanks

Wim

Hi Wim,

I'm facing the same problem where two of my monitors are connected to the dock using DVI-I and DVI-D respectively and the one with DVI-I is showing the lag with my laptop (Lenovo YOGA-13) running Windows 8 enterprise version.

It's the worst user experience. Please help.

-Rmvm

[jme]

Sorry for the delay. Yes! I just checked this with the video method you mentioned Wim. Video + mouse froze at same time.

ALSO though, the mouse speed lags without video problems. For example, I move the mouse around and it doesn't always move at the same pointer speed. Sometimes it moves very, very slow and has this "lead" feeling to pointing around. I have the mouse settings on my computer for "Motion Settings" all the way to fast. Sometimes I have to pick up my mouse to get it to move to the other side of the screen... (meaning I have to pick it up, move it to the right side of my mouse pad, then move it again to the left to get it to track across the screen all the way to the left).

[Sean33]

I'm on a similar set-up getting mouse lag and blurry icon/text when connected to my port replicator.

Set-up:
Lenovo X1 Carbon Touch running BIOS 2.53
Lenovo USB Port 3.0
2 Samsung 2043BWX Monitors connected via DVI
Running DisplayLink Driver 7.2.46733.0 - This is what is showing after installing the most recent 7.2 M1 drivers

Experience:
The mouse feels like it is running on a low FPS setting. Similar to the mouse movement you get your system drags running a video game at low FPS. There are input delays and mouse freezes. Working with this lag is near impossible for long periods due to always having to do tiny movements in the mouse to correct for the lag.

Fuzzy images text occur when there are changes on the screen. The best example is changing folders in Outlook. Clicking on a new folder results in all the text in the program flickering through two or three different levels of blur. This also happens to taskbar icons.

I'm not seeing the video hang ups other are reporting, the system as a whole just seems to be running very slow.

little update....

I found another mouse in the closet - was using a Microsoft wireless keyboard 3000 v2 and Microsoft wireless mouse 5000 that use a single dongle.

I got out another mouse - Microsoft wireless mouse 5000 that has a separate dongle to itself. Working fine so far! Will update if it degrades.

Updated to the latest 7.2 M1 drivers and still experiencing the same behavior.

Hi All

I've attached a development build of 7.2 M1 but includes a fix for the momentary screen freezing that I suspect is responsible for some of the "mouse freezing" or "mouse lag" posts on here.

As a reminder, if you are using a wireless mouse, make sure you are not getting USB 3.0 interference as covered in this article (http://www.displaylink.com/support/ticket.php?id=340).

Please let me know if this improves the mouse behaviour.

Hi All

I've attached a development build of 7.2 M1 but includes a fix for the momentary screen freezing that I suspect is responsible for some of the "mouse freezing" or "mouse lag" posts on here.

Running now for about 45 minutes, and the stutter appears to be gone! I'll report back if I see any glitches.

Regarding wireless mouse interference, I experience issues when my Logitech Unifying USB receiver is plugged directly into one of the USB 2.0 ports (on the back of the Plugable UD-3000). No idea why, as I thought that the interference was limited to the 3.0 ports. I have the receiver on a 3 foot USB extension cable, physically placed about a foot from the Plugable, and it works fine... Go figure.

[alexg57]

I've been troubleshooting the lag and blinking issues for a week now, just finding this thread today. Good timing - I tried Wim's pre-release drivers and things are better. The blinking when docking Xbox Music on the side in Windows 8 no longer happens, and the general mouse lag does feel better. I wouldn't say it's as smooth as working directly on the laptop (Dell XPS 12), but it's within the realm of acceptable now.

I look forward to further improvements!

Update a few hours later: looks like I spoke too soon. Although the lag is maybe a little better, it's still noticeable. The blinking to black is there, too, but it's different now. It seems to blink more quickly and less often than before. Also, I'm running two DVI monitors and one of them only has the Zune client in "tiny" mode to play some music. When I hit the Windows key to bring up the new start menu, there's a definite pause for a second.

[Galactican]

Wish I could report an improvement but I'm still in the same boat. If anything I would say it maybe even got a little worse with that update.

I really appreciate the effort though! Nice to see a company posting potential fixes like this within a thread rather than making their users wait.

I see from an earlier post you are using the Lenovo X1. Can you check all the drivers are up to date on this platform, including the BIOS and see if this makes a difference. I think I saw a user earlier in this thread who found this helped.

Also, make sure you are using the "High Performance" power profile, rather than "Balanced" when plugged in. This could also slow down our software's performance.

Wim

[alexg57]

After some playing around, including the pre-release driver Wim posted and doing the crazy USB 3.0 driver hack, the mouse lag problem is almost gone for me. I think it's close enough that I'll be able to look past it while we wait for a rock solid driver. If no docking were like running a game at a constant 60 frames per second, it now feels like 60 FPS with an occasional dip to 50 FPS. Not terribly significant, but it's there.

You know what the biggest difference has been? As mentioned by Wim, changing the power mode to High Performance. It's strange, though, because my Balanced profile has everything set on the highest performance settings when plugged in. The High Performance profile must do other stuff under the hood that can't be controlled with the UI. When I switch to Balanced, the mouse will skip around when moving over Outlook. In High Performance, it's pretty much as smooth as when not docked. Weird, but I can handle having to switch when docked. Obviously it's not ideal, but it works.

Give it a shot and post your results.

So the development BUILD posted by Wim is newer than the 7.2M1 posted on the displaylink website? I too have the mouse getting stuck randomly for a few seconds.

Edit: UPDATE
Ok so the BUILD is newer and supposedly fixes the mouse freezing issue but brings back the horrible screen rendering. Minimizing a window or switching between classic and modern UI (Windows 8) is just quite bad. The mouse pointer speed also suffers. *Sigh*

[ThePhantom]

Not posting to refute the experience of others -- but my install of the development driver is still going strong on my Lenovo Twist with Windows 8 (64-bit). For the record, my earliest install of the Windows drivers was M0, I've manually run the DL install (vs. using Windows update) for the M1 update, and I never attempted the USB driver tweak, despite M0's problems.

Granted, my install is still fairly stock, but the differing experience of others here is a little disconcerting. It'll certainly give me pause with future software updates, as things appear to be somewhat frail...

[jme]

Just wanted to update - not going to install this beta driver since my issue is fixed... Simply using a new dongle and mouse (one not shared with my keyboard) has helped! Not sure of the exact root cause but the mouse is back to normal.

It should not have regressed the fuzziness that was seen before. What is your system spec? Have you tried "High Performance" mode if you have a tablet with this setting, as it could help.

Thanks. Never mind, I did a reboot of the dock and now it seems good. Hopefully it will stay this way. I have the X1 Carbon Touch and Windows 8 Enterprise OS.

Edit:
With the next release of drivers can we possibly have some more acceleration as far as mouse pointer sensitivity goes? It's good now but there is that slight light feel of slowness with the pointer. I am using the High Performance power profile.

[mike]

Well unfortunately with these pre-release drivers I also saw the regression to image fuzziness as well as it not helping with the lag issue. Wasn't any better or worse so I just reverted back to the standard M1 drivers now and the image fuzziness is gone. Lag is still present of course.

Heck of an issue here. I don't envy you guys for sure!

[henrybakker01]

Still having lags and a disappearing mouse cursor with my HP Envy X2 en HP 3005PR USB Port Replicator.

Tried the latest version available on the site, and the latest Beta-version mentioned in this post. No difference.

Besides, if I only use the external screen and disconnect the port replicator my Envy gets an BSOD. First the display driver isn't responding anymore en than a BSOD occures.

[tfennel]

Same setup as before - I've been through the beta drivers posted here as well as the updated drivers Lenovo released on their site on the 5/22ish. Still really bad.

Now all I have to do is be editing a Word document and if I type quickly (which I do usually), the fuzziness takes over the screen - pretty much impossible to deal with constantly like this and stay productive.

There must be a fix coming for this? I can help with repros, logs, etc, if someone wants. I am more than happy to contribute to the solution as I have a 100% consistent repro in many common day to day scenarios.

I have upgraded all drivers and BIOS. I'm using the new driver WIM posted and changed power settings to high performance.

Yep.. still laggy and slow I am afraid. I am on high performance power plan, beta build, Win 8 Ent.. heck I tried every single driver they have listed.

I hope you can fix it.

Bizarre. I'm using a Twist (low-rent X1 ;) ), Win 8, with a Plugable dock -- and I'm still living large.

Are you using a wireless mouse? If so, try sticking the receiver on an USB extension cable. That made all the difference for me (still don't quite know why, as the receiver was plugged into a presumably interference-free 2.0 port).

I don't know much about the Lenovo dock, other than that the reviews on Amazon scared me enough to scoop the Plugable instead. Given that they ultimately all use the same driver set, I'd be surprised if Lenovo could have botched it up that badly, but then again... :eek:

This is why your wireless mouse works now: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html

(sidenote: how the hell did they agree to this protocol with that large of a glaring bug)

I was using a wireless mouse, but stopped months ago because of that interference nonsense. I'm now using a wired one.

my mouse lags and jumps across the screen instead of moving smoothly. I have to choose to either use the mouse and dual monitors and suffer, or try to get my work done on a 14" screen. ugh. This is been going on too long.

[ThePhantom]

This is why your wireless mouse works now: http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html

Yes -- the DisplayLink guys here cite this issue frequently. The odd thing in my case is that the Plugable's USB ports on the rear of the unit are 2.0 ports, yet the problem still exists when plugged directly into those. I presume that the USB 2.0 and 3.0 ports on the front may share the same ASIC, and perhaps the interference is using the traces to the 2.0 rear ports as a wireguide for the interference. Or, maybe they're *all* 3.0 ports, and they just don't label the rear ones as such -- I dunno...

Sorry to hear that your rodent experience is still poor, even with the wired mouse. Is there any latency with, say, reading/writing to a USB key or hard drive? I wonder if the bus on your Lenovo dock is behaving poorly entirely, or just with HID devices...

[xijio]

Something happened recently. Now my computer is basically unusable while docked. The mouse lag is insanely bad to the point that it jumps across the screen an inch at a time. The network performance is degraded so webpages and files load very slowly. Moving windows around the screen stupidly slow. It was working ish for the past few weeks and the mouse would only freeze once every few seconds now it is like I'm using a 10 year old computer even though it is a top of the line lenovo.

It has been MONTHS since this problem was identified. The amazon reviews show that everyone hates this crap and its ruining your reputation. Please give this problem the attention it is clearly widespread and clearly a major problem. I can't do my job because of this and that isn't okay.

As I'm typing this sentance the characters are bunching up and appearing in groups because the shitty displaylink software can't keep up with the input. It s currently using 8-10% CPU and all I'm doing doing is typing on a webpage. It feels like I'm working over a shitty VNC connection on dialup.

<snip>
Hate to say it, but perhaps the thing to try is a non-Lenovo dock. Given that all these docks use the same DL chipset (and their associated drivers), you would think that they'd behave remarkably similarly.

While my initial experience with the Plugable UD-3000 was a little rocky at first, it's been operating very well recently. I frequently swap between my MacBook Air and the Lenovo Twist, and things generally don't miss a beat (the exception being the missing USB 3.0 sound on the Mac side, coupled with some wired ethernet quirks on the Mac). GigE, Logitech Wireless mouse, a power hungry IBM Model M mechanical keyboard (with PS/2 to USB adapter), 1920x1080 DVI display... All just fine.

While I jokingly referred to Lenovo botching things in an earlier post, perhaps it's not a joke after all -- given that Lenovo has nearly smashed their solid IBM heritage to bits, it wouldn't be entirely surprising.

Perhaps Wim, or the other DL guys here, can possibly suggest whether something Lenovo has done (fatally in the hardware, or perhaps in some custom firmware for their dock) could contribute to the misery that's posted here.

Quick question for all affected users:

Are you using one monitor or two? I'm using two and I'm thinking maybe it's a USB bandwidth issue on Windows 8?

[ThePhantom]

Quick question for all affected users:

Are you using one monitor or two? I'm using two and I'm thinking maybe it's a USB bandwidth issue on Windows 8?
I (unaffected user) use 1, as the Plugable only has 1 DVI port anyway (and I'm sort of out of desk space :) )

A single uncompressed 32-bit DVI signal should consume about 3Gb/sec -- the DVI/HDMI spec has provisions for 10Gb/sec, however. Clearly, 2 X 3Gb would outpace USB 3.0's 5Gb/sec, but... my understanding is the DL drivers are compressing the video signal prior to sending out over USB. In addition, I assume they're only transmitting deltas, making bandwidth consumption fairly low. My only evidence of this is the fact that an older USB 2.0 computer runs acceptably well in the same configuration...

Windows pro 8

Upgrading to 7.2 MI display driver seemed to fix the mouse lag, but introduced (much worse) intermittent screen blurriness. Can last anywhere from a few to many seconds..

Have experimented with :
changed DisplayLink manager priority to high
Swopped out wireless mouse / keyboard for wired ones.
Upgraded BIOS (and all other upgrades via Lenovo System Update)

Don't really know where to go from here. Its enough of an issue to make working on a separate display impossible.

[Embo]

Switching from the bottom port to the top port fixed this issue [holding thumbs]. not sure what would happen if i tried to use a second display

[mike]

I've got the issue whether I use one external display or two. Same behavior.

[roeebar]

Same here (Lenovo X1 Carbon). Even after updating to 7.2 build above - mouse jumps are still an issue. Changing the power plan to "High performance" might help a little. Fuzzy image problems are "solved" after Windows restart.

[JesseAaronSafir]

Hey everybody! I just read this whole thread. I have been frustrated for months with the same issues as everyone else. Here's my setup:

All the latest Lenovo driver, BIOS, firmware updates installed via Lenovo System Update 5

I have experienced the horrible intermittent fuzziness on my monitors. At times the fuzziness would affect one monitor at a time but at other times it would affect all monitors at the same time. And at other times the intermittent monitor fuzziness would go away completely for a while. But when my computer is working properly, I'm very hesitant to undock it or shut it down in fear that the problems will return. I have also had very frustrating mouse freezes and keyboard unresponsiveness where keystrokes are missing. I tried using a USB extension cable to put the 2.4GHz wireless receiver inches from my mouse and keyboard but that hasn't helped. I have noticed that if my cell phone (HTC Evo 3D) is anywhere near my keyboard, it seems that the keyboard and mouse problems get worse.

I have the latest drivers and firmware installed for the Lenovo USB 3.0 dock and I installed the latest DisplayLink drivers directly from DL. I also have the latest video driver directly from NVIDIA for the Quadro FX 880M. I set my power plan to "High performance" and it does seem to have helped somewhat but not completely resolved the issue. The "Processor power management"->"Minimum processor state"->"Plugged in" setting is at 100%.

Also, I've tried running everything through the single USB 3.0 connection back to the ThinkPad W510. In other words, I have only the Lenovo USB 3.0 dock plugged into he ThinkPad and then all other USB devices, audio, Ethernet, DVI connections are all running through it. The reason I run it this way is that I found that when I plugged other USB devices directly into the ThinkPad (such as hard drives, iPod, Android phone), it would cause the displays (connected to the Lenovo USB 3.0 dock) to flick off to black temporarily.

It looks like this idea wouldn't apply in my case since my eXtensible USB 3.0 Host Controller is "Renesas" instead of "Intel"?
http://plugable.com/2012/12/01/windows-8-and-intel-usb-3-0-host-controllers

And yes, this is USB 3.0 2.4GHz wireless interference is VERY interesting:
http://www.displaylink.com/support/ticket.php?id=340

I already have my 2.4GHz keyboard/mouse receiver about 3 feet from the ThinkPad W510 (with several USB 3.0 ports) and the ThinkPad USB 3.0 dock and yet I still get interference that causes the keyboard and mouse to not work consistently. I could, for now, plug the 2.4GHz wireless receiver into the ThinkPad W510's USB 2.0 port. That might help. But going forward, I thought I'd only be using one USB port to connect to all my peripherals. I will be getting a Lenovo ThinkPad Helix soon and was planning to connect it to the USB 3.0 dock. I wonder if it's okay to have the USB 2.0 2.4GHz wireless receiver connected to a USB 3.0 port at all?

I haven't tried the attached 7.2M1 "with freezing fix" DisplayLink drivers yet. I'll probably try that next.

In theory, is there any reason that I shouldn't be able to run multiple DVI displays off a single USB 3.0 connection (currently I have 3 external DVI displays) as well as a USB 3.0 hard drive, USB 2.0 hard drives, keyboard/mouse, webcam, GigE Ethernet, USB audio?

[JesseAaronSafir]

Wim...what's the driver version of the one you posted as an attachment. Is it newer than 7.2.47873.0 from 2013-05-10?

Edit: I downloaded it and found that it's 7.2.48041.0, which is newer. The build date is 2013-05-16. I'll try that now then.

Okay so I've tried installing 7.2.48041.0 but I can't get Windows 8 Enterprise 64-bit to use these drivers. It said it installed successfully and rebooted but Device Manager still shows Driver Version 7.2.46733.0 from 2013-03-19 installed. I've even tried uninstalling all Lenovo USB and DisplayLink drivers, telling Windows to delete the drivers, rebooting, and then reinstalling from this installer but it still keeps putting back the old drivers. I'd love any tips about how to get the latest drivers installed.

OK - There seem to be a number of different issues being raised in this thread, but with the same symptoms.

For those that are still seeing mouse lag (or more correctly, the screen freezing for a second or so when moving anything around the screen) can you try the 7.4 beta for Windows 8.1

This includes a further fix for this issue, that seems rarer, but could be affecting some of the users on this thread:

[Timbiotic]

I had some of the lag and fuzziness, tried the beta drivers and pc would not boot at first, then started turning on and off the USB 3 docking station. Completely removed these 7.4 drivers and installed the ones from the web page 7.3. With the high performance setting I can live with it. Not sure what causes 7.4 to go crazy. Will try again on next release.

[acidfire52]

I have updated to the latest BETA driver, works OK, but still laggy and slow.
I am running a Lenovo Helix
Win 8 Pro
Lenovo USB 3.0 Dock, using LAN, both DVI, and 2 USB 2.0.
2x Lenovo 1920x1080 monitors
All drivers and firmwares up to date

It works OK for me. Screen slows down some times, scrolling is universally slow. Moving my scroll wheel, pauses before actually scrolling down.
The whole desktop experience feels slow running on this dock. Mouse is slow, always hesitates when moving. Actually has a delay when you move you mouse over icons in the task bar.

It is usable, just barely, but not enjoyable at all.

[mike]

Just installed the 7.3 drivers. For now I'm not seeing any lag on my external monitors. Things seem to be working much snappier.

I'll update later with more time under my belt with these drivers.

[mike]

Interesting find: I get lag with certain applications/sites. For instance, if I open the "Wunderlist" website (using IE or Chrome) I get very noticeable mouse lag. Other websites on another tab (say Google News) show no lag. That's what happens on my external monitors. If I move the browser window to my laptops native screen the mouse lag totally disappears.

So it seems that some sites/applications could be using some sort of code that's just really unfriendly to the Displaylink Drivers.

Pretty weird...

[acidfire52]

An update for me.
It seems to have settled down. After running for a day, my mouse is at pretty much normal speed. Any lag isn't noticeable anymore unless I really look for it.

setup reminder:
Lenovo helix, Lenovo USB 3 dock, 2x 1920x1080 monitors, using the gigabit LAN and 2 USB 2.0 devices.

Only real slowdown I get now is when transferring large amounts of data over the LAN, also through the dock, it will get a bit fuzzy, but not a big deal.

Thanks for all the work.

I'm experiencing exactly same issue (big lag in mouse movements). I've installed latest driver but still no help.

Setup:
- Lenovo X1 Carbon
- ThinkPad USB 3.0 dock
- 2 screens running 1920x1200
- Gigabit Ethernet cable connected
- Wireless mouse and keyboard receiver connected to the dock
- DisplayLinkManager v. 7.3.49122.0


Some observations (I didn't bother read through all of the posts in the thread so sorry if there are some duplicates):
- DisplayLinkManager eats up ~20% CPU (seems mostly kernel time)
- Updated driver doesn't seem to help at all
- lag is gone if I connect mouse / keyboard receiver directly to the laptop (not through the dock)
- with no receiver DisplayLinkManager CPU usage is down to 3~5%


For now I'm happy with the workaround (connect mouse and keyboard receiver directly to the laptop), but it'd be really nice if this issue got solved.

[skomialek]

Hi Wim,

Thanks for the reply. You're right. I misinterpreted the problem since it started as I had mouse connected to the USB 2.0 hub connected through the ThikPad dock (which was I believe caused by the fw). I then connected to directly to USB 3.0, problem persisted (or even got worse) so I updated the firmware. Now it is connected back to the USB 2.0 hub and the problem doesn't occur.

Thanks for help.

I've read through a good portion of this thread and wanted to add my experience.

Setup a Yoga 13 for a user yesterday, their config is:
Yoga 13
Lenovo USB 3.0 Dock
Display Link 7.3 drivers
Two 27" Samsung monitors at 1920x1080

Only things plugged into Dock were keyboard/Microsoft Arc mouse (wireless)

Mouse lag was bad, it made the setup unusable. I found the article about Intel's study on 2.4ghz devices and USB 3.0 so I switched out the wireless mouse to a wired one. User said the lag is much better and hasn't reported it as being an issue still (yet).

So, if you are having lag issues and using a wireless mouse then start by swapping it for a hardwired one (as Wim has suggested).

[elfuego]

I also have the issue described in the first post. Brand new Lenovo x1 carbon running on windows 8, USB 3.0 hub, 2 displays connected with wired keyboard and mouse.

I experienced a very unpredictable mouse lag, very sluggish performance while moving around active windows. Then I followed the instructions here:
http://www.displaylink.com/support/ticket.php?id=346

and the effects have gotten from bad to worse - the external monitors now do a mini-blink whenever I type anything on a keyboard and occasionally there are graphical glitches (similar to ones when you overclock a graphics card too much). Of course, in addition to very slow performance. :(

Is there any help to this issue finally?

Edit: Fixed - the problem was that the hub was connected to the USB 2.0 port instead of USB 3.0. The X1 carbon has 1xUSB 2.0 and 1xUSB 3.0 connector. Not both are USB 3.0 :-/

I have the issue, have un-installed the older version, installed the latest but still sloppy display and mouse response on my 2nd screen.

Config:

Lenovo Carbon X1 (non-touch)
Windows 7 Home Premium 64
Lenovo USB 3.0 Hub
Logitech AnyNet wireless mouse and keyboard
2x external Samsung 24" 1900x1200 monitors via hub via DVI
1x external Hanns-G 17" 1400x900 monitor via mini HDMI-VGA converter directly from laptop

I've been struggling with mouse and keyboard lag across all three external screens, regardless of whether I use the wireless mouse or the laptop's built-in touchpad and keyboard. I'm running the latest Lenovo drivers for the laptop, the latest BIOS update, the latest USB Hub software and firmware.

The issue of mouse and keyboard lag seemed to be affecting everything I did on my laptop so long as I was plugged into the USB 3.0 hub from Lenovo. Turning off monitors reduced the lag but didn't eliminate it. I've applied the suggested power settings, I've moved my wireless mouse to an extender and kept the receiver far from the USB 3.0 cables and ports. I've also plugged the mouse into the secondary USB 2.0 port on the left side of my chassis, far from the USB 3.0 cable.

On a hunch, I went into the BIOS and changed my USB 3.0 speed settings from "Automatic" to "Enabled." With ALL other fixes suggested in this post now applied, I now have a fairly successful setup with 4 monitors. I can run video on one monitor, a web browser in another, and an excel document in yet another. This is excellent.

However, I notice that SOME web sites cause a little bit of lag. I'm not sure this has ANYTHING to do with DisplayLink or my multiple monitor setup. Sites that have busy scripting like Facebook or NBCNews seem to be the easiest sites to replicate the problem. However, simple sites like Google or Reddit don't cause any lag.

So, without further adieu, I'll confirm this problem resolved for me. Please let me know if you have any questions about my configuration if you'd like to attempt to emulate my blissful world of mediocrity. :D

Hi,

I bought a Targus USB3.0 dock a couple of days ago and I have some slight laggy problems too. Yesterday I also had the problem of fuzzy screens but I fixed that with some Lenovo driver updates.

The laggy issues seems to occur only in the browser (Google Chrome, also in Firefox). When I click the address bar it's taking a second to select the text in it. Also when I click a bookmark folder it takes a second to show me the content of it. This is not unmanagable but nevertheless not that pleasant ;)

My setup:
Lenovo Yoga 13, i7, 8gb ram
24" dual monitor setup (at the moment 1 plugged in directly, 1 through dock but is the same as plugging them both into dock). No wireless devices are connected.

Hey People!

I also treated myself with a Targus DisplayLink dock. I experienced the same lags with the wireless keyboard and mouse. It seems that I found the fix for my issues.

I have an Asus Zenbook UX31E ultrabook. I also upgraded to Win8.1 Pro and I didn't pay much attention for checking hw installation as everything worked at the first boot.

However my ultrabook is equipped with a Fresco Logic USB3 controller. Windows installed a Microsoft-made driver for it. As I changed the driver to the Fresco make, all my problems disappeared!
Check your hw configs and see whether the right usb controller driver is installed!
Fresco LoGic driver:

I installed the above drivers and it didn't help with the mouse lag.
My mouse is still not smooth and its extremely annoying.
I tried plugging the mouse into the usb port on the laptop and that didn't help.
Is this a graphics issue?

-- Update 04/11/2014 --
I plugged the hub into the USB 3.0 port and now the mouse is ok. Seems that I was plugging the hub into the 2.0 port which caused the degraded performance.
